GOLF BALL.

Application filed October 5, 1923. Serial No. 666,842.

To all wlw/m t may cof/wem:

Be it known that I, THOMAS W. MILLER, a citizen of the United States,residing at Ashland, county of Ashland, State of 0h10, have inventedcertain new and useful Im proveniente in Golf Balls, of which thefollowingis a speoication.

My invention relates to golf balls, and compositions therefor, and is acontinuation in part of an a plication for golf ball compositions, filedNo. 561,943, and has for its objects, first, economy in the manufacture,at the same time producing a ball which will have to a `veryconsiderable degree all of the desirable qualities of golf balls now onthe market,` and, secondly, to eliminate the liability of cutting theball if topped or struck with the edge of the driving club when in play.l

In. the accompanying drawing:

lIhe figure is an enlarged sectionalview of my improved golrn ball.y

In car ing out my invention, I iirst prepare a, ru ber stock 1 frommaterial suitable to produce a composition of the desired gravity,cutting, as hereinafter set forth. After millingand preparing saidstock, it is cut into sections each of substantially the weight of afinished golf ball, and each of said seetions then is placed inregistering molds and heated and vulcanized under pressure. Said moldsare provided either with projections or de ressions to produce thedimple or bramble e ect as desired, so that the ball 'so compressed andvulcanized as i* 'comes from the mold will have the true exterior designof the finished ball, andalso will have the same diameter less thevthickness of the cover. After vulcanization and removal from said moldany selvage or overflow at the line of mold registration is r noved, andthe ball then is cleaned from all undesirable sub stances by boiling ina suitable solution.

The object of applying the dipped cover y me May 18, 1922, Serialdensity, resiliency and resistance to' 2 is to provide a comparativelyhard unyielding surface, the variation of which 4in thickness affectsthe distance flight of the ball, and also its rebounding propertiesafter striking the ground. A further ob- ]ect is to provide the desiredcolor for the finished ball.

From the above description, it willl,be uner of a thickness which willdestroy theA sharp outline of the surfacedesign, the ball after thedipped cover has been applied again can be placedin a mold of a propersize land design, and by applying heat under pressure, the surfacedesign will be brought out more sharply. 4

A. composition which will produce a ball closely approximating thestandard ball in its functions embodies the following ingredients andapproximate proportions:

Pounds.

Rtubber 32 Glue 18 Zinc, oxide 10% Sulphur It has been found that a,composition of the above formula when vulcanized will resist cutting toa very high degree, and this result is accomplished primarily throughthe 'use of the rubber and glue ingredients. It

will be understood, however, that I do not limit myself to theseproportions, as the glue and rubber' content may be varied somewhat, andcertain fillers, such as aluminum liake and asbestos added, withsatisfactory results.

Vhile I prefer to form the ball solid, it will be understood that thesame may be formed' with a hollow center.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is':- 4.

1.` A golf ball, comprising a homogeneous body portion embodying as acomposition,

lis

rubber, glue, a vulcanizing agent, and a filler in such proportions aswill approximate the standard ball in size and Weight, saidbody portionbeing formed and vulcanized to the surface configuration,v of thefinished ball,` and a thin cover or finishing coat which conforms tosaid surface configuration.

2. A golf ball, comprising a homogeneous body portion embodying as acomposition,A rubber, glue,f`a vulcanizing agent, and a filler in suchproportions as will approximate the standard ball in size and weight,saitl body portion being formed and vul-` canized to the surfaceconfiguration of the finished ball,fand a thin dipped cover or finishingcoat which conforms to said surface configuration.

3. A golf ball, comprising a homogeneous bod portion embodying asa'composition, rub r, glue, a pv-ulcanizing agent, and a filler insuchproportions as will `approxi` mate the standard ball infsize andWeight, said body portion being formed and vul#y canizecl to the surfaceconfiguration of ythe finished bal1,`and a thin dipped cover orfinishing coat containing a`-.pig1ne1it fv tion.

LA Vulcanizable composition for golf balls, comprising rubber,

glue, a filler, and a vulcanizin agent, in such proportions as, whenforme into a ball substantiall 1.62l in diameter, will Weigh, with thenished coatinglor covering.. approximately 1.62 ounces` 5. Avulcanizable composition for golf balls, comprising rubber, glue, afiller, and a vulcanizing agent, in suchy proportions as, when formedinto aball substantially 1.62 in diameter, will weigh, With the finishedcoating or covering,l approximately 1.62 ounces, and possessing a properresiliency and a high resistance to cutting.

b'. A vulcanizable Composition-.for golf] rubber approximately 32 balls,comprising parts, glue approximately' 18 parts, zinc oxide approximately10.5 parts, and sulphur i approximately 2.5 parts.k
